Boxing up rectangular prisms

A rectangular prism has rectangles for its bases as well as its sides. Because all the surfaces of a rectangular prism are rectangles, you can actually turn it so that any pair of parallel sides are the bases. Pick your favorites. 

The Problem What is the height of a rectangular prism that has a square base 6 inches on a side and a volume of 288 cubic inches  

Use the formula for the volume of a prism replacing the Fwith the 288 cubic inches, the / with 6, and the w with 6. Then solve for h. 

The Problem A rectangular prism has a length that s twice the width and a height that s twice the length. If its volume is eight times the height, then what is the volume  

using the formula for the volume, V = Iwh, filling in the equivalences and solving for w,
